The seismic response of stone blocks, simply superimposed to each other with plane and dry connections, are mainly dominated by three mechanisms: pure sliding, pure rocking of a single block or systems of blocks and a simultaneous occurring of the two. Among many different stone structures, the highly non-linear response of a multi-drum stone column has been studied. A prototype column, ideally representing a 1:4 scaled model of the original belonging to the colonnade of the temple of Mars Ultor in Rome, has been tested under a number of natural ground motions, selected in a large database of real records. The peculiar dependency of the column response on the characteristics of seismic input has been studied in the shaking table tests performed at the EUCENTRE. Thanks to more than hundred different tests on a large specimen, it has been possible to correlate the observed response mechanisms to the characteristics of the input signals.
